Apply to a clean cloth and then use the cloth to clean
the surface.
Do not use any type of abrasive cleanser as it may damage
or scratch the surface.
Fitting the bonnets
1. Your GMC grinder/sander/polisher comes with a polishing
bonnet. The polishing bonnet is used for buffing and
finishing the surface.
2. To fit the polishing sponge,
press and hold the spindle
lock button (2) and screw the
polishing sponge onto the
spindle.
3. The polishing bonnet features
a drawstring attachment to fit
the bonnet over the polishing
sponge.
4. Place the bonnet over the
polishing sponge so that the
outer edge can be drawn over
the top of the disc.
5. Carefully tighten the
drawstring around the
polishing sponge and secure it
with a simple overhand knot.
6. Tuck the drawstring into
the bonnet.
7. Remove the bonnet by loosening the drawstring and
slipping the bonnet off the polishing sponge.
Applying polish
Most polishes are either in paste or liquid form. Before
using any polish read all directions on appropriate
applications and proper use.
Switching on and off
IMPORTANT. When in polishing mode set the variable
control to the slowest speed (position 1) for the best result.
Never faster.
1. To start the tool, first ensure the disc and tool are in good
condition. Plug the cordset into the mains socket.
2. To start the tool, depress the lock-off button (8) and
squeeze the on/off trigger switch (7).
Note. Once the tool has started there is no need to maintain
pressure on the lock-off button.
3. Do not overload the tool so that the disc slows down. Let
the tool do the work rather than applying pressure. The
weight of the tool alone provides sufficient pressure.
4. After completing the application, turn the polisher off. To
turn the tool off let go of the on/off trigger switch (7). The
lock-off button (8) will re-engage.
The tool will stop. (Please note that the disc continues to
spin for a few seconds even though the switch is turned
off). Keep hands well away from the moving disc. Wait
until the disc stops rotating before lifting the grinder/
sander/polisher from the surface.
Holding and guiding the tool
1. Always clamp the work piece where applicable.
2. Before starting the tool, first ensure the polishing sponge,
polishing bonnet and the tool are in good condition.
Plug the cordset into the mains socket.
3. Do not overload the tool so that the disc slows down. Let
the tool do the work rather than applying pressure. The
weight of the tool alone provides sufficient pressure.
4. Hold the tool securely and make sure that you have full
control at all times.
5. During the buffing operation, maintain an angle of 15–20
degrees between the tool and the work piece.
